Energy performance contracting (EPC) allows organizations to implement energy efficiency projects through guaranteed savings contracts. An energy services company (ESCO) conducts energy assessments and implements efficiency upgrades like lighting, HVAC, and building envelope improvements. The ESCO guarantees that the energy savings will cover the costs of the project without upfront capital from the client. EPC provides clients capital improvements, utility funding opportunities, guaranteed savings, and other benefits. The U.S. Department of Housing and Urban Development also offers incentives for public housing authorities to pursue EPC through programs like frozen utility baselines and additional operating subsidies. Case studies show EPC projects achieving substantial energy and cost savings.
